High carbohydrate food has been perceived as a food with high glycemic index (GI). Meanwhile, the risks of diabetes are frequently associated with the GI carbohydrate based foods. Therefore, a comprehensive study based on the literature review regarding the relationship between high-carbohydrate food and the glycemic index needs to be conducted. High-carbohydrate foods can be grouped into the available carbohydrates type and non-available carbohydrates type. Food with available carbohydrates such as glucose, disaccharide, digestible oligosaccharides, and starch have positive correlation with t

Carbohydrates are crucial for living cells, playing myriads of functional roles that range from being structural or energy-storage devices to molecular labels that, through non-covalent interaction with proteins, impart exquisite selectivity in processes such as molecular trafficking and cellular recognition. The molecular bases that govern the recognition between carbohydrates and proteins have not been fully understood yet. In the present study, we have obtained a surface-area-based model for the formation heat capacity of protein–carbohydrate complexes, which includes separate terms for the

Abstract: Carbohydrates are widespread in biological systems and are often associated with many specific recognition and signaling processes that lead to important biological functions and diseases. Considerable efforts have been directed toward understanding and mimicking such recognition processes, and developing effective agents to control these events. The pace of discovery research in glycobiology and development of carbohydrate-based therapeutics, however, has been relatively slow compared to that of other classes of biomolecules due to the lack of appropriate strategies and methods avai

Rice contains a high amount of carbohydrates, proteins, vitamin B, vitamin E, phytic acid and inositol. While the rice protein and carbohydrate are regarded as a good source of food in nutrition with its non-allergic characteristics, the application of rice by-products (RBP) in food industry has been limited to animal feed. This study, therefore, was conducted to increase the amounts of insoluble rice protein and rice dietary fiber in RBP by hydrolyzing carbohydrates in RBP using various commercial carbohydrases.

Birds were fed three diets formulated from either fruit, insect, or seed. We predicted that SI carbohydrases and peptidases would be modulated in direct correlation with relative levels of dietary carbohydrate and protein, respectively.

AbstractThe purpose of the present review is to describe how human physiology at very low carbohydrate intakes relates to the criteria for nutritional essentiality. Although we did not limit ourselves to one particular type or function of carbohydrates, we did primarily focus on glucose utilisation as that function was used to determine the recommended daily allowance. In the general population, the human body is able to endogenously synthesise carbohydrates, and does not show signs of deficiency in the absence of dietary carbohydrates.

The use of carbohydrates as drugs and vaccines has several limitations. Molecular mimics of carbohydrates provide an alternative source of compounds to target pathways involving protein-carbohydrate interactions. In recent years, immunological studies have demonstrated the ability of certain peptides to act as molecular mimics of carbohydrates, in that they are able to induce an anti-carbohydrate immune response. Carbohydrate-mimetic peptides that bind to enzymes and lectins have also been discovered. The nature of this mimicry at the molecular level is currently the subject of investigation.

Carbohydrates, one of the most important compounds in living organisms, perform numerous roles, including those associated with the extracellular matrix, energy-related compounds, and information. Of these, polymeric carbohydrates are a class of substance with a long history in drug delivery that have attracted more attention in recent years. Because polymeric carbohydrates have the advantages of nontoxicity, biocompatibility, and biodegradability, they can be used in drug targeting, sustained drug release, immune antigens and adjuvants.

The present research describes a simple and inexpensive derivatization method that uses acetylation to address the challenges associated with the quantification of the ten most common carbohydrates. The derivatization reaction has two periods : (1) The oxime formation of carbohydrates was carried out at 15 minutes, 500 µL of NH2OH 2.5% and 60 ºC and (2) acetylation of carbohydrates was carried out at 45 minutes, 600 µL of AAA and 80ºC. Most of the carbohydrates generate single peaks via chromatographic separation, except fructose, which generates a double peak. The procedure was successfully a

The production of glycoproteins with carbohydrates of defined structure and minimal heterogeneity is important for functional studies of mammalian carbohydrates. To facilitate such studies, several Chinese hamster ovary mutants that carry between two and four glycosylation mutations were developed. All of the lines grew readily in culture despite the drastic simplification of their surface carbohydrates. Therefore, both endogenous glycoproteins and those introduced by transfection can be obtained with specifically tailored carbohydrates. The lectin resistance properties of the mutants showed t

Bananas can be used in many classroom lab activities to make carbohydrates easier for students to understand. I detail a simple series of banana activities that can be used to investigate carbohydrates across a wide range of levels of organization and that serve to connect carbohydrate concepts that might otherwise seem disparate to students. For example, the taste of a banana is linked to carbohydrate hydrolysis, as well as to organelle content within banana cells. Bananas can be used safely in any classroom, and inquiry-based learning can be used to progress through related course content. I

Currently, the carbohydrate-restricted diet is very popular. Atkins' book, Dr. Atkins' Diet Revolution, has sold millions in its more than 25 years of existence. His book promotes the carbohydrate-restricted diet, which focuses on the consumption of proteins and fats as primary calorie and energy sources, while severely restricting carbohydrates. However, when carbohydrates are restricted from the diet, the body's primary energy source is reduced considerably. Therefore, the purpose of this study was to compare the psychological responses to exercise of individuals when on a carbohydrate restr

Disaccharidases are enzymes of the small intestine, and they are essential for normal carbohydrate digestion. Carbohydrates are an important dietary component, providing about half of the calories in a typical Western diet. The smallest carbohydrate units, the monosaccharides, are the building blocks for more complex sugars and starches. The monosaccharides of dietary importance include glucose, galactose, and fructose. Carbohydrates are present in an average diet, primarily in the form of dissacharides (two monosaccharides linked together) and starches (glucose polymers). The disaccharide lac

Maturation of mechanisms for carbohydrate absorption occurs in a defined sequence during human fetal development. The intestinal enzymes, lactase, sucrase, maltase, isomaltase, and glucoamylase, are at mature levels in the term fetus. Mature levels of pancreatic amylase activity and glucose transport occur postnatally, and levels are low in both the term and preterm neonate. In the preterm infant, sucrase, maltase, and isomaltase are usually fully active, but lactase activity, which increases markedly from 24 to 40 weeks, may be low depending upon fetal age.

Multivalent carbohydrate–lectin interactions are essential for a multitude of biological recognition events. Much effort has been spent in the synthesis of potent multivalent scaffolds in order to mimic or inhibit biological carbohydrate–protein interactions. However, the defined spatial presentation of carbohydrates remained a challenging task. Peptide nucleic acid (PNA)- and DNA-based double helices are useful scaffolds that enable the controlled display of carbohydrate ligands in a modular approach. The hybridization of PNA-sugar conjugates with complementary DNA strands provides multivalen

Abstract: The biological relevance of sulfur containing carbohydrates is gaining substantial attention. Thus the new developments, especially in the synthetic and medicinal chemistry of thio-sugars are critically important for carbohydrate drug design. New studies of biological processes including bio synthetic reactions and enzyme control mechanisms, discovered during the last few years clearly contributed to an understanding of their biological roles. These roles of carbohydrates and thio sugars in particular through biological processes and diseases are becoming better understood now. The
